Abstract

The angular and wavelength selectivity characteristics of holograms written with a tunable pulsed dye laser and a cw argon laser were measured. A hologram in a 0.05% weight iron doped crystal was shown to possess ~40% broader bandwidths than a hologram written in a nominally pure crystal of the same thickness. Analyses based on these bandwidths indicate a 430–500-μm effective hologram thickness in a 1-mm thick crystal, which is of the order of the absorption length (380 μm). The implications of these results with respect to optical memories are discussed.
